Mars rover technology could improve solar power efficiency on Earth Telegraph

Solar panels could be kept free from dust and grime which hampers energy output using a self-cleaning system developed for NASA’s Mars rover robots.
The devices scouring the red planet have sensors which detect dust build-ups and zap the surface of their solar panels with an electrical charge to keep them shiny. Dr Malay Mazumder, who helped create the technology for NASA, said it could help boost efficiency of large solar power plants, many of which are situated in arid and dusty desert locations.
